Beechcraft King Air 260 vs Beechcraft King Air 360er vs Daher Tbm 960

The Beechcraft King Air 260 and King Air 360ER are both twin‑engine turboprop business aircraft, while the Daher TBM 960 is a single‑engine turboprop designed primarily for fast owner‑pilot and light corporate missions. In category terms, the King Airs emphasize redundancy and cabin versatility (including more “true cabin” space and mission flexibility), whereas the TBM 960 emphasizes speed and efficiency with a smaller cabin footprint. On range, the King Air 360ER is the long‑leg specialist of the three, offering the greatest endurance for longer nonstop segments compared with the King Air 260 and typically more than the TBM 960, depending on payload and reserves. The King Air 260 provides strong midsize mission range but is not optimized for maximum long‑range ferry capability like the 360ER. The TBM 960 delivers solid range for a single‑engine turboprop, but it generally trails the 360ER and may be closer to the 260 depending on configuration. For passenger capacity, the King Air 260 and 360ER commonly seat more people in typical executive layouts than the TBM 960, which usually carries fewer passengers due to its narrower cabin and seating arrangement.
